Well, AFTER fixing some compile errors it worked for me. Are you compiling as a windows gui app?

What compiler?

Error:

case IDC_about:
MessageBox(hwnd,"empty string!","Warning",
MB_OK);

Also I got a redefinition error on IDC_HELP so I renamed it, but didn't look for the original definition. Might be a good idea to add some #ifndef macros in the header files.

[edit:] Also that font is a little big, didn't quite fit the text in the buttons.
